The mill is powered by two 5500 hp D.C. motors. Nominal mill speed is 10.7 r.p.m. (78% critical) with a top speed of 11.3 r.p.m. The mill discharges through a grate with 3″ pebble ports onto a 14′ dia. x 13′ trommel screen with ¾" openings. On January 19, 1991 the mill was brought on line as a fully autogenous mill without pebble crushing.

System of semi-autogenous grinding (SAG) mill is modeled in this work based on circular-disk objects, which represents not only the ground materials but also the mill liners. Interaction between these objects is through linear spring dash-pot force, which is solved numerically in soft-sphere scheme using molecular dynamics (MD) method. There is also force due to earth gravity.
